The Great German Pilgrimage of 1064–1065 was a large pilgrimage to Jerusalem which took place a generation before the First Crusade.
It originated in the part of the Holy Roman Empire that today is called Germany in 1064, and was led by Archbishop Siegfried of Mainz, Bishop William of Utrecht, Bishop Otto of Ratisbon (modern-day Regensburg), and Bishop Gunther of Bamberg. There were between seven and twelve thousand pilgrims on the journey. The pilgrimage passed through Hungary, Bulgaria, Patzinakia, and Constantinople, just as the First Crusade would over thirty years later, with similar results: the pilgrims were treated harshly wherever they went, and were ushered off into Anatolia once they reached Constantinople.
They passed through Anatolia, which had not yet been conquered by the Seljuk Turks, as it was by the time of the crusade. Their troubles increased when they reached Latakia; there they met other pilgrims who warned them of the dangers to the south, and when they reached Tripoli, Lebanon, they were attacked by the emir of the city, but were saved by a storm which they regarded as a miracle.
On Holy Thursday they reached Caesarea, and on Good Friday they were attacked by Bedouin bandits. According to the longer version of the Annals of Altaich William of Utrecht was killed in battle, (although he actually survived and lived until 1076). The pilgrims fled to a nearby fort. On Easter Sunday the Bedouin leaders met with Gunther there and agreed to a truce, but the Bedouins threatened to kill the pilgrims anyway. Gunther had them killed and hung over the walls as a deterrent to further attacks.
